If you're looking for usable advice, we gotta know more about your situation. Otherwise, that's a very wide open question.
Presume you are single. How old? What is your profession and when would you need to work again?
What would you have to sell? House/cars/stocks/personal stuff? Should you sell those items and what is the cost of doing so? Would that net you enough, and for how long? Have you saved enough for retirement?
What about health care? What about visas?
Lots to think about. Let's say you decide to go for it. What's your "business" plan? How much will you start with? What do you need to buy to get started?
Now for your travel and expenses. Where will you stay? Camping, hostel, or hotel? How much will you ride each day? Can you DIY your repairs and service or do you need to see a dealer? Lots of questions to answer whether you can survive on your anticipated budget.
Now, what happens if something goes astray: the bike gets totaled or you get injured. What's your backup plan?
Finally, what does it look like when you are done? Meaning, when will the "great ride" come to an end, and when it does, what will you need after it ends?
If you are going to get serious about this, you've gotta have a plan.
